[0029] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0030] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0031] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0032] Existing drum-type washing machines are usually provided with a door body that rotates to open. One side of the door body is hinged to the door frame of the washing machine body, and the other side is locked by a lock structure that can be opened and closed. The lock structure used to lock the door body includes a lock tongue fixed on the door body and a lock box installed on the washing machine body. For the sake of aesthetics, the lock box is usually set on the inner side of the door frame of the washing machine body to hide it. At the same time, it is necessary to set a socket corresponding to the lock box on the door frame. When the door body is closed, the lock tongue passes through the socket on the door frame and extends into the washing machine body and locks with the lock box. This structure has certain defects: after opening the door body, the socket on the door frame is exposed, and substances such as washing powder, washing liquid, and water can easily fall into the washing machine body through the socket, which poses a risk of clogging, contamination, and corrosion to the lock box and other components in the washing machine body.

[0033] In order to overcome the above technical problems, the present embodiment provides a washing machine door lock structure, including a lock tongue 21, a lock box and a blocker 3, the lock tongue 21 is installed on the door body 2 of the washing machine; the lock box is installed on the inner side of the door frame plate 11 of the washing machine body 1, and is used to lock the lock tongue 21 to fix the door body 2 on the door frame plate 11; the blocker 3 is arranged on the inner side of the door frame plate 11, and the door frame plate 11 has a socket 111 allowing the lock tongue 21 to be inserted, and when the door body 2 is in the open state, the blocker 3 automatically blocks the socket 111; when the door body 2 is in the closed state, the lock tongue 21 passes through the socket 111, pushes open the blocker 3 and extends to the inner side of the door frame plate 11 and is locked by the lock box.

[0034] In this embodiment, a blocker 3 that can be controlled by the insertion state of the lock tongue 21 is provided on the inner side of the door frame plate 11 of the washing machine body 1. When the door body 2 is opened, the blocker 3 will automatically block and seal the hole 111 on the door frame plate 11, effectively isolating the inside and outside of the door frame plate 11 from the hole 111, and effectively reducing the risk of impurities falling into the washing machine body 1 through the hole 111 and causing the internal lock box and other components to be blocked, contaminated, and corroded.

[0035] The lock box and the plugging device 3 are installed on the inner side of the door frame plate 11, which does not mean that they must be fixed directly on the door frame plate 11. They can also be fixed to other structures in the housing of the washing machine body 1, as long as they can be kept fixed and hidden by the door frame plate 11. Of course, according to specific design requirements, the lock box and / or the plugging device 3 can also be fixed to the inner wall surface of the door frame plate 11.

[0036] During specific implementation, in order to ensure that the blocker 3 can accurately and reliably block the socket 111, a simple driving mechanism can be designed, such as using a connecting rod, a lever or a cam mechanism to convert the movement of the locking tongue 21 into the action of the blocker 3. When the locking tongue 21 is inserted, the blocker 3 can be pushed away so that the socket 111 opens and the locking tongue 21 can be smoothly inserted; when the door body 2 is opened and the locking tongue 21 is separated, the blocker 3 can automatically reset and block the socket 111.

[0037] In order to ensure sealing, the occluder 3 should have a sealing structure whose shape and size match the insertion hole 111 to ensure that the occluder 3 can completely cover the insertion hole 111 to prevent impurities from entering.

[0038] In one embodiment, the blocker 3 includes a mounting seat 32, a blocking member 31 and an elastic reset member. The mounting seat 32 is fixedly installed in the washing machine body 1. The elastic reset member connects the mounting seat 32 and the blocking member 31 to push the blocking member 31 toward blocking the socket 111.

[0039] The mounting seat 32 is the fixed part of the plug 3, which is fixedly mounted on the inner side of the door frame plate 11 of the washing machine body 1. The design of the mounting seat 32 should ensure stability and reliability, and be able to withstand the force of the plug 31 and the elastic reset member. The plug 31 is a component actually used to plug the socket 111. When the door body 2 is in the open state, the plug 31 automatically blocks the socket 111 under the action of the elastic reset member to prevent substances such as washing powder, washing liquid, and water from entering the inside of the washing machine body 1 through the socket 111. The plug 31 should be made of suitable materials, such as flexible materials such as rubber or silicone, to ensure that it can fit tightly to the socket 111 and provide a good sealing effect. The elastic reset member is a component connecting the mounting seat 32 and the plug 31, and is used to push the plug 31 toward the plug 111. The elastic reset member is usually made of elastic materials such as springs and elastic sheets. When the door body 2 is closed, the lock tongue 21 passes through the insertion hole 111 and pushes open the blocking piece 31, and the elastic reset piece is compressed or stretched at this time; when the door body 2 is opened, the elastic reset piece releases its stored energy, pushes the blocking piece 31 to reset and re-block the insertion hole 111.

[0040] In one embodiment, a rotating shaft 33 is provided on the mounting seat 32, and the blocking member 31 includes a swing arm 312 and a plug 311 adapted to the socket 111, and one side of the two opposite sides of the swing arm 312 is fixedly connected to the plug 311, and the other side is rotatably installed on the rotating shaft 33; the elastic reset member includes a torsion spring 34, and the torsion spring 34 is sleeved on the rotating shaft 33 to push the blocking member 31 to rotate in the direction of blocking the socket 111.

[0041] The blocking member 31 adopts the form of rotating opening and closing, which has the advantages of smooth and reliable opening and closing and easy structure implementation. Figure 5 When the lock tongue 21 is inserted into the insertion hole 111, the lock tongue 21 pushes the blocking member 31 downward, and the plug 311 of the blocking member 31 deviates from the insertion hole 111, so that the lock tongue 21 can be smoothly inserted, and the torsion spring 34 stores energy during this process. Figure 3-4 When the locking tongue 21 is separated from the insertion hole 111, the torsion force of the torsion spring 34 drives the blocking member 31 to swing upward, so that the plug 311 blocks the insertion hole 111 again. The torsion spring 34, as an elastic reset member, has high reliability and durability, and can maintain a stable elastic force for a long time, ensuring that the blocking member 31 can always accurately block the insertion hole 111. The design of the plug 311 can be closely adapted to the insertion hole 111, providing a good sealing effect, and preventing impurities from entering the washing machine body 1.

[0042] In one embodiment, referring to Figure 6Two parallel sliders 35 are slidably mounted on the mounting seat 32, and the two ends of the rotating shaft 33 are rotatably connected to the two sliders 35 respectively; the elastic reset member includes a linear spring 36, one end of which is fixed to the mounting seat 32, and the other end is connected to the slider 35, so as to push the slider 35 and the blocking member 31 to move in the direction of blocking the socket 111.

[0043] In addition to the rotational opening and closing method, the blocking member 31 also combines the form of linear reciprocating movement. When the lock tongue 21 is inserted, the blocking member 31 can be pushed downward for a short distance, and then the lock tongue 21 pushes the blocking member 31 to move horizontally, so that the blocking member 31 can completely deviate from the insertion hole 111. Obviously, in this structure, the blocking member 31 only needs to deflect downward for a short distance, and the space required to be reserved between the blocking member 31 and the lock box to allow the blocking member 31 to swing downward is smaller, so the lock box can be closer to the door frame plate 11, improving the compactness of the washing machine structure. In summary, this solution can effectively ensure the compactness of the washing machine structure on the premise that the blocking member 31 can completely deviate from the insertion hole 111 to open the insertion hole 111.

[0044] When the door 2 is opened and the locking tongue 21 exits the insertion hole 111, the linear spring 36 pushes the slider 35 and the blocking member 31 to move toward the insertion hole 111, and the torsion spring 34 drives the blocking member 31 to swing upward, so that the blocking member 31 blocks the insertion hole 111 again to prevent impurities from entering the washing machine body 1.

[0045] In one embodiment, referring to Figure 7 A stopper 351 is provided on one side of the slider 35 close to the swing arm 312 , and the torsion spring 34 has two torsion arms 341 , one of the torsion arms 341 abuts against the stopper 351 , and the other torsion arm 341 abuts against the swing arm 312 , so as to continuously provide torque to the swing arm 312 .

[0046] Based on the structure of the slider 35, a stopper 351 is provided thereon which can be used to support the torsion arm 341 of the torsion spring 34. The linear sliding of structures such as the torsion spring 34, the stopper 351, the slider 35, the rotating shaft 33 and the blocking member 31 are all synchronized, which can ensure that the blocking member 31 can slide to any position, and the torsion spring 34 can provide torque for the blocking member 31 to achieve a reliable torsional function.

[0047] In one embodiment, the mounting base 32 includes a tail plate 321 and two guide rails 322 connected in parallel to one side of the tail plate 321 , and guide grooves 3221 are respectively provided on opposite sides of the two guide rails 322 , and the two sliders 35 are respectively installed in the two guide grooves 3221 .

[0048] This design enables the slider 35 to stably slide in the guide groove 3221 , thereby ensuring that the blocking member 31 can accurately move to block or open the insertion hole 111 .

[0049] In one embodiment, one linear spring 36 is disposed in each of the guide grooves 3221 , and two linear springs 36 are connected to two sliders 35 , respectively.

[0050] A linear spring 36 is disposed in each guide groove 3221 , and the two linear springs 36 are respectively connected to the two sliders 35 . Such a design further enhances the stability and reliability of the movement of the two sliders 35 , ensuring that the blocking member 31 can accurately and reliably block the socket 111 .

[0051] In one embodiment, a bottom plate 323 is connected between the bottom sides of the two guide rails 322 , and the bottom plate 323 can limit the downward swing angle of the blocking member 31 .

[0052] A bottom plate 323 is connected between the bottom sides of the two guide rails 322. The bottom plate 323 serves to limit the downward swing angle of the blocking piece 31. This design not only improves the connection between the guide rails 322 and enhances the reliability of the mounting base 32, but also avoids unnecessary space occupation or damage caused by the blocking piece 31 swinging too far downward.

[0053] In one embodiment, a plurality of mounting holes are provided on the tail plate 321, and a plurality of connecting columns corresponding to the mounting holes are provided on the inner wall of the door frame plate 11. The connecting columns have threaded holes, and connecting bolts pass through the mounting holes and connect the threaded holes to fix the mounting seat 32 to the inner wall of the door frame plate 11.

[0054] The mounting seat 32 is fixed to the inner wall of the door frame plate 11 by connecting bolts, so that the blocking member 31 can be close to the insertion hole 111 to block the insertion hole 111, which can make the structure compact and effectively ensure the reliability of the installation of the blocking member 3.

[0055] On the other hand, a washing machine is provided, comprising the above-mentioned washing machine door lock structure.

[0056] Based on the washing machine door lock structure of this embodiment, the washing machine of this embodiment also has the ability to effectively isolate the inside and outside of the door frame plate 11 from the socket 111, effectively reducing the risk of impurities falling into the washing machine body 1 through the socket 111 and causing the internal lock box and other components to be blocked, contaminated, and corroded.
